What does ORD X indicate in relation to targeting?

The designation ORD X specifically refers to the distance from the target along the gun-target line. This term is crucial in battlefield operations as it helps determine how far the artillery units are from their intended target while taking into account the trajectory and angle of the fire. Understanding this measurement allows for precise calculation of firing solutions, ensuring that munitions can be accurately delivered to engage enemy forces or targets effectively. This information is essential for tactical planning and coordination among joint fire support elements, ultimately contributing to mission success.
